Afterward, the wastewater flows into sedimentation ponds, which come in various types such as vertical flow and horizontal flow. In the sedimentation ponds, gravity causes the larger flocs formed by coagulation to settle at the bottom of the pond, while the supernatant fluid flows out from the top, achieving solid-liquid separation. This equipment effectively removes suspended solids, some heavy metals, and organic matter from water, playing a crucial role in various fields such as industrial wastewater treatment and municipal wastewater treatment, improving water quality and reducing the pressure on subsequent treatment stages.
